For what values of x, the numbers are in G.P.?

Given:

_{For the given Sequence to be in G.P. Common ratio between two adjacent numbers in the sequence should be equal.}

That is: Common ratio between = Common ratio between

⇒ (1)² = x²

⇒ x =

∴ For the given sequence to be in G.P. x should be .

The 4^th term of a G.P. is square of its second term, and the first term is – 3. Determine its 7^th term.

Which term of the following sequences:

(A)

(B)

(c)

Find the sum to indicated number of terms in each of the geometric progressions in

0.15, 0.015, 0.0015,... 20 terms.

Find the sum to indicated number of terms in each of the geometric progressions in

terms.
